Definitions

  • a noise-reducing capsule for receiving a fan motor unit of a vacuum cleaner.
  • This fan motor unit is for generating an air flow to provide a suction force of the vacuum cleaner.
  • gers and includes a blower fan and an electric motor for driving the blower fan.
  • the noise-reducing capsule comprises a molded foam part z. B. from a mixed or closed-cell foam, said molded foam part forms a mechanical support of the fan motor unit relative to a blower motor unit enclosing the vacuum cleaner housing.
  • the noise-reducing capsule forms a flow channel for the air flow emerging from the fan motor unit
  • the noise-reducing capsule can furthermore also be used to reduce turbulence in the air flow emerging from the vacuum cleaner housing. The minimization of such turbulences also leads to a significant reduction in noise emissions of a vacuum cleaner.
  • the fleece or the filter foam is arranged as a diffuser in the flow channel formed by the noise-reducing capsule.
  • the noise-reducing capsule is substantially airtight, so that of the fan motor unit generated air flow can emerge from the capsule essentially only by the flow channel formed by the noise-reducing capsule.
  • the foam of the capsule is preferably closed-celled, but at least mixed-celled.
  • the flow channel is jointly formed by the vacuum cleaner housing and the capsule, then here too the flow channel is advantageously designed such that an air flow guided in the flow channel is deflected at least once, preferably several times through an angle of 90 ° or greater.
  • the flow channel is collectively formed by the vacuum cleaner housing and the capsule, it has proven to be advantageous if the vacuum cleaner has acting as a diffuser elements which reach into the flow channel.
  • the elements acting as a diffuser can be assigned to both the vacuum cleaner housing and the capsule or advantageously form a mechanical unit with the vacuum cleaner housing or the capsule. In addition, they can also form a mechanical unit with the fan motor unit.
  • the vacuum cleaner housing of a generic vacuum cleaner has an outflow opening for the suction power providing air flow, which is generated by the fan motor unit.
  • the capsule is now arranged in the vacuum cleaner housing relative to the outflow opening and the fan motor unit such that the cap is covering the outflow opening with respect to the motor.
  • direct sound emissions of the fan motor unit which are directed towards the discharge opening of the vacuum cleaner housing, can be effectively reduced.
  • An even more effective reduction of this direct sound radiation of the blower motor unit through the discharge opening of the vacuum cleaner housing can be achieved in that the capsule has at least one region of increased density, which is arranged in the installed position of the capsule where the capsule covers the outflow opening above the engine. This embodiment therefore represents an advantageous development.
  • the resulting skin layer can on the one hand promote or provide an advantageous airtightness of the molded foam part as already mentioned above. Furthermore, this skin layer can serve to provide a region of increased density of the molded foam part, which may be advantageous to form capsule areas with locally increased acoustic insulation effect.
  • a fleece, a filter foam or a plastic film is introduced into the cavity of the foaming tool, which is subsequently backfoamed.
  • a capsule can form, which comprises a fleece, a filter foam or a plastic film, which are each captively connected to the capsule.
  • FIG. 1 is a schematic sectional view of a generic vacuum cleaner
  • FIG. 5 schematically shows a three-dimensional representation of a vacuum cleaner 1 according to the invention, in which the engine compartment 20 with inserted and opened capsule 70 and blower motor unit 50 arranged therein can be seen.
  • the capsule sub-half 84 is positively received in the engine compartment 20 of the vacuum cleaner housing 10, which forms an additional internal partition 22 for this purpose.
  • the fan motor unit is received in a press fit.
  • the fan motor unit 50 is secured against twisting in the capsule 70 about the axis of rotation of the motor 54 by a stabilizing member 58, not shown in FIG.

Abstract

L'invention concerne une capsule insonorisante (70) servant à loger un bloc moteur de soufflerie (50) d'un aspirateur (1). Le bloc moteur de soufflerie (50) est conçu pour produire un flux d'air et délivrer ainsi une force d'aspiration à l'aspirateur (1), et comprend un ventilateur de soufflerie (52) ainsi qu'un moteur électrique (54) entraînant le ventilateur de soufflerie (52). L'invention concerne par ailleurs un aspirateur (1) équipé d'une capsule insonorisante (70).
